Bearded dragons can eat broccoli, but it should only be given in moderation. Broccoli contains goitrogens, substances that can interfere with the thyroid function by affecting iodine uptake, which can be harmful if consumed in large amounts. Therefore, while broccoli is rich in vitamins A and C, calcium, and fiber, it should not be a staple in a bearded dragon's diet.

To safely include broccoli in their diet, offer it as an occasional treat rather than a regular meal. It's important to chop it into small, manageable pieces and mix it with other vegetables to ensure a balanced diet. Leafy greens, like collard greens and dandelion greens, are better primary options. Always monitor your bearded dragon's health and consult with a veterinarian if you notice any signs of dietary imbalance or health issues.
